Automatically copy client's address

This is a small part of a screen from an Order Entry
system. The user can select the customer at the top of screen in the
drop-down list; after selection, the customer's address and phone number are
displayed for reference.

My client delivers the ordered item to their customer or to any
other address. If it's to go to their customer, they can click the
"customer" button and the system will automatically copy the
customer's address to the ship-to address.

Before clicking the "Customer" button

(Customer info is at the top; order info is at the bottom)

After clicking the "Customer" button

(Customer info is at the top; order info is at the bottom)

The buttons that are blurred out are to automatically copy the address for
several storage yards to the "ship-to" address.
